ES中接到请求后，通过查询解析器,解析查询串⽣成对应的查询。
1.指定单个字段查询
displayNameEn包含james或者curry的
也可是使用and
POST /nba/_search
{
"query": {
"query_string": {
"default_field": "displayNameEn",
"query": "james OR curry"
}
}
}
2.指定多个字段查询
这里的先后顺序没有关系
POST /nba/_search
{
"query": {
"query_string": {
"fields": [
"displayNameEn","teamNameEn"
],
"query": "Rockets and james"
}
}
}
